Officers were called to the area of Morgan Road and Alley 88 for a report of an assault in progress around 8:40 p.m. Tuesday.

Police said a man told them he saw his 40-year-old wife on the ground after being approached and punched by two women.

The man chased them both off and was ultimately able to detain the suspect until officers arrived. Police said the suspect, identified as 21-year-old Mary Ellen Carr, was arrested and charged accordingly.

The other robber fled north on Morgan Road on foot and police said after a search they were unable to find her. She is described as a white woman, about 5 feet 4 inches to 5 feet 6 inches tall with a thin build, wearing a dark sweatshirt and blue jeans.
